WIRE-NAIL SPECIFICATION forming part of Letters Patent No. 350,357, dated October 5, 1886.

Application filed June 5, 1886.

To all iuhom it may concern:

Be it,known that I, Tnannnus FowLnn, a

citizen of the United States, residing at Shelton, in the county of Fairfield and State of:

useful Improvements in \VireNail Machines; and I do hereby declare the following to be a full, clear, and exact description of the invenart to which it appertains to make and use the same. I

My invention relates to certain new and useful improvements in machines for making wire nails, and while it can be advantageously employed for the production of the loose wire nails which are in common use, it is more es-- peeially adapted for making string nails of the character set forth and described in Letters Patent of the United States granted to me the 4th day of May, 1886, and numbered 341,413.

IVith this in view my invention consists in the details of construction hereinafter fully set forth, and then recited in the claims which form a part hereof.

I11 order that those skilled in the art to which my invention appertains may fully understand the construction and operation of my machine, I will now describe the same, referring by letterto the accompanying drawings,which form a part of this specification, and in which?- Figure 1 is a plan view of my machine; Fig. 2, a front elevation; Fig. 3, an end elevation, looking from the left of Fig. 1; Fig. 4, a section at the line 00 x of Fig. 1, looking in the direction indicated by the arrow '0; Fig. 5, a section at the line 3 9 of Fig. 1, looking in the direction indicated by the arrow 10; Fig. 6, a detafil cross-section through the dies and bars, ant showing the device for the support and adjustment ofthe lower pointing-die; Fig. 7, a plan View of the die-bars and posts, the levers being removed; Fig. 8, a short length of completed nails, and Fig. 9 a detail plan of the die-bars and dies.

Similar letters denote like parts in all the figures of the drawings.

A is the bed-plate, and B are legs upon which itis supported. In suitable bearings, 0, formed at the back of the bed-plateis hung and adapted to revolve the main shaft D, which receives Serial No. 204,236. (No modeL) which I have not thought it necessary to Show in the drawings.

E are standards mounted upon and projecting upward from the bed-plate, and F are two lovers pivotally hung to said standards, as seen at Figs. 4, 5, and G. The rear ends of levers F, which are preferably provided with shoes, rest upon and are actuated by a cam, G, on the main shaft. Beneath the levers are arranged two pairs of die-bars. Those lettered H have formed or secured therein graspingdies. Those lettered I are similarly provided with dies tapered as to their operating surfaces, and adapted not only to grasp the wire, but to compress it to form the point of the nail. (See Figs. 9 and 6.) lie'supon the surface of the bed-plate, and its rear end is secured to a short post, J, projecting'upward from the bed-plate. The upper grasping-die bar is pivoted to the post J, so that it may swing vertically away from the lower grasping-die bar. The pointing-die bars are similarly secured to a post, K, which in the form of a short shaft is extended downward through the bed-plate, as shown at Fig. 5. This arrangement of the pointingdie bars gives. to them not only a vertical opening movement upon the post K, but also a lateral movement toward or away from the graspingdie bars upon the journaled post as a pivotal point.

A spring-actuated bar, L, (see Figs. 5 and.

7,) is secured on the bottom of post K, and tends to hold the pointing-die bars away from the grasping-die bars. The extent of the separation just mentioned is determined by a screw, M, threaded through one of the standards, as seen at Figs. 1, 6, and 7.

Sprin N,interposed between the two grasp ing-diears, and also between the two pointing-die bars, serveto keep them normally separated vertically. (See Figs. 4. and 5.)

O are links through which the downward movement of the levers F is transmitted to the die-bars to close the latter. They are employed to permit motion vertically to both facilitate the movement last referred to, athird link, I is employed to support the lower pointing-die bar. Said link stands in a hole ICO in the bed-plate, and isadj ustable for wear by a screw, Q, threaded into the hole from beneath, and upon which the link stands. As will be readily understood, the raising of the rear ends of the lovers F by the cam 011 the main shaft closes both pairs of dies vertically. The movement of the pointing-die bars toward the graspingdie bars against the'spring action of the bar L is effected by means of the pivoted block R, an extension of which abuts against the pointing-die bars, the toggle-levers S, the follower T, resting upon the bed-plate, and the cam U on the main shaft, which operates through the follower to straighten the toggle-joint. The follower and toggle-levers, after each action of the cam, are returned to their normal position by a spring.

The feeding of the wire in my machine is accomplished as follows: A lever, V, is pivoted to the bed-plate, as seen at Figs. 1 and 3, and is oscillated upon its pivotal point against the action of a spring, \V, (seen at Fig. 3,) by a face-cam, X, on the main shaft. A lever, Y, whose rear end is engaged by a peripheral cam, Z, is pivoted to the side of lever V, and is as a whole carried thereby. The forward extremity of the lever Y carries a serrated jaw, A, and this, by the action of the cam Z upon the rear end of said lever, is caused periodically to bind the wire between it and an extension, B, of the lever V. \Vhen the wire is so grasped, the action of cam X. carries both levers forward. lVhen the face-cam ceases to act, the lever Y is thrown up out of engagement with the wire by a spring, 0, placed beneath it, and both lovers are thrown back by the spring \V to take a fresh hold.

The trimming mechanism of my machine consists of a friction-roller, a, secured on cam G, a lever, 11, secured to the face of standard E and curved at its rear end for engagement with the friction-roller, a bracket, (Z, secured to standard E, a cutter, a, sliding in ways formed in the bracket (Land having a V-shaped and longitudinally-tapered cutting-edge, a cut tor-block, f, and a spring, 9, against which the lever bis raised. The cutter is adj ustabl y secured to and carried by the lever 11.

The operation of my machine when organized as above set forth is as follows: The wire is fed from a coil or reel through suitable straightening-rolls, and passes through the machine from rightto left. When between the dies, both pairs, through the medium of the lovers, links, and cam on the main shaft, are caused to close tightly upon it. As the normal position of the die-bars (determined by the spring act-ion of bar L) is with the pointing-die bars separated from the graspingdie bars, it follows that when the dies are closed there is a short length of wire between their vertical surfaces. The pointingdie bars are now, by the block, togglelcvers, follower, and cam, forced up against the grasping-die bars, and the short length of wire is upset into a head, which is suitably flattened between the vertically-abutting faces of the four dies.

At the completion of this operation the diebars are separated in both directions by the action of springs N and spring-bar L. At this time the feed lays hold upon the wire and draws it forward the proper distance for the next operation of the dies.

Having thus described my inventiomwhatl claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a machine of the character described ,with the drivingshaft and cam thereon, of a pair of grasping die bars and dies mounted upon the bed plate, and a lever engaging with the main cam and operating to close said dies, a pair of pointing die bars and dies alongside the grasping-dies and similarly operated, and means, as described, whereby the pointing-dies may be given alateral movement against thegraspingdies, sub stantially as set forth.
